 A tool for CN XCPC contests
 
-- 全平台远程代码打印
-- 支持封榜期间发放鼓励气球的小票机
+- 代码打印和小票机打印（全平台支持）
+- 支持封榜期间发放鼓励气球
+- 支持连接 DOMjudge 与 Hydro 系统，同时亦可独立运行
 - 选手机赛时数据监控与屏幕监控
 
 TODO Features：
 
 - [ ] 更好的选手机座位绑定
-- [ ] 支持多平台参赛系统
-- [ ] Windows 小票机支持
 - [ ] 优化 UI 顺畅度
 - [ ] 使用 WebSocket 返回指令执行情况
 - [ ] 支持全考场监视

 #### Balloon
-服务支持 `Fetch Mode` 下的气球推送，支持 `Domjudge` 与 `Hydro` 系统，支持 `Domjudge` 与 `Hydro` 系统的 `Balloon` 推送，同时若赛事在封榜后仍然推送气球，则支持自定义鼓励气球数，高于设定值则不推送，为所有队伍打造优质赛场体验。

 #### Monitor
 服务支持监控选手机情况和监控服务器桌面，如您需要选手机监控，可通过设置 Systemd 定时执行任务等多种方式定时执行 `monitor` 命令，如需监控服务器桌面，请在选手机上提前运行 `vlc-camera` 和 `vlc-desktop` 服务， CAICPC 镜像已经内置了这三两个服务，您只需在选手机上运行即可，如您为自己的镜像，可从 `https://github.com/hydro-dev/xcpc-tools/blob/main/scripts/monitor` 下载 `monitor` 服务。
